Affectionately known as "The Professor" for his encyclopedic knowledge of the game and long hours of research before each broadcast, Van Wieren spent 33 years with the Braves before retiring in 2008, shortly after the death of his longtime partner Skip Caray.

"The Atlanta Braves are deeply saddened by the passing of Pete Van Wieren," the team said in a statement. "He was such a large and important part of our organization. We and all of our fans across Braves country fondly remember his soothing voice calling our games for 33 years. Our thoughts and prayers are with his wife, Elaine, his children and his grandchildren."

A native of Rochester, New York, Van Wieren had been calling games for the Triple-A Tidewater Tides when the Braves hired him before the 1976 season to join a new three-man broadcast team with Caray and Ernie Johnson.

The trio would soon become known to baseball fans around the nation thanks to Turner, the team's brash owner, who began beaming games via satellite on a once-obscure Atlanta television station. While the team didn't have much success through the 1970s and '80s, Johnson, Caray and Van Wieren were the faces and voices of the game in areas that didn't have their own local broadcasts.

With his thick glasses and thinning hair, Van Wieren didn't fit the classic television mold. But his soothing voice and ability to come up with obscure statistics in the pre-Internet era paired well with Caray, who was known for his biting sarcasm and witty retorts. The two were inducted into the Braves Hall of Fame together in 2004, joining their good friend Johnson, who had previously been inducted. He died in 2011.

Van Wieren's talents went beyond baseball. He also called NBA games on TBS and TNT, in addition to stints with the NBA's Atlanta Hawks, NHL's Atlanta Flames and Big Ten Conference football.

In 2010, he released a memoir of his long career, "Of Mikes and Men: A Lifetime of Braves Baseball."

Van Wieren was initially diagnosed with lymphoma in early 2010. He was cancer-free for several months, but the disease returned the year was out.

"This is certainly not what I planned to do when I retired," he told MLB.com at that time.

Van Wieren is survived by his wife of 50 years, Elaine, sons Jon and Steve, a daughter-in-law and three granddaughters.
